How it works and installation - Install on the rear wheel. When the rider pedals, energy is transferred through the chain to the flywheel. The inertia of the flywheel stores this energy, turning the rear wheel and helping to move the bicycle forward. Key benefits - Smoother ride: The flywheel’s inertia smooths pedal power, reducing cadence fluctuations and delivering a steadier feel. - Energy storage and assistance: Stored energy is released to assist propulsion as needed, improving ride quality on varied terrain. - Durable construction: Made from carbon steel with high wear resistance, high strength, durability, and enhanced endurance. - Reliable hub connection: High-precision threads ensure a tight connection with the hub, enabling smooth operation, accuracy, reliability, and good overall performance. Material and durability - Material: carbon steel with superior wear resistance, high strength, and long-lasting durability. Endurance is improved. Installation and compatibility - Connection: high-precision threads provide a tight hub connection, supporting smooth operation, accuracy, reliability, and solid performance. Use scenarios - City commuting on rough or uneven roads to achieve a smoother pedal feel and consistent forward motion. - Uphill riding and long climbs where maintaining momentum is beneficial. - Rides on varied terrain where smoother cadence and energy assistance contribute to comfort and efficiency.
